  cyclocondensation reactions leading to C-glycosylated dihydropyridines (DHPs) has been investigated. A three-component approach with an anomeric sugar aldehyde (galacto, manno, and ribo derivatives), a β-keto ester, and an aminocrotonate afforded C(4)-glycosylated DHPs in high yield (70–90%).

  Tacripyrines (1-14) have been designed by combining an ACNE inhibitor (tacrine) with a calcium antagonist such as nimodipine and are targeted to develop a multitarget therapeutic strategy to confront AD. Tacripyrines are selective and potent ACNE inhibitors in the nanomolar range. The mixed type inhibition of hAChE activity of compound 11 (IC50 105 +/- 15 nM) is associated to a 30.7 +/- 8.6% inhibition of the proaggregating action of ACNE on the A beta and a moderate inhibition of A beta self-aggregation (34.9 +/- 5.4%). Molecular modeling indicates that binding of compound 11 to the ACNE PAS mainly involves the (R)-11 enantiomer, which also agrees with the noncompetitive inhibition mechanism exhibited by p-methoxytacripyrine 11. Tacripyrines are neuroprotective agents, show moderate Ca2+ channel blocking effect, and cross the blood-brain barrier, emerging as lead candidates for treating AD.
• 2-(2-Aryl-2-oxoethylidene)-1,2,3,4-tetrahydropyridines. Novel isomers of 1,4-dihydropyridine calcium channel blockers

  The title compounds are novel double bond isomers of 1,4-dihydropyridine-type calcium channel blockers (CCB). These derivatives were prepared by using the Hantzsch dihydropyridine synthesis. The assignment of structure was based on spectroscopic data and a regiochemically unambiguous synthesis. Several of the analogues inhibited [3H]nitrendipine binding with IC50 values as low as 25 nM. By comparison, nifedipine, a clinically useful 1,4-dihydropyridine CCB, inhibits [3H]nitrendipine binding with an IC50 of 1.6 nM. In the Langendorff rat heart preparation, treatment with the more potent derivatives produced marked dose-related increases in coronary flow with little or no effect on heart rate or contractility, except at the highest concentrations tested. The selectivity for vascular versus cardiac effects was similar to that of nifedipine, i.e., the concentration producing vasodilation was approximately 2 orders of magnitude lower than the concentration eliciting cardiodepression. These novel isomers extend the structure-activity relationships for calcium channel blockers into a series closely related to the 1,4-dihydropyridines.
• Synthesis of 6-amino-1,4-dihydropyridines that prevent calcium overload and neuronal death

  The synthesis and pharmacology of 6-amino-1,4-dihydropyridines, such as ethyl 6-amino-4-aryl-5-cyano-1,4-dihydro-2-methyl-3-pyridinecarboxylic acids (3-16) and 2-amino-4-aryl-7,7-dimethyl-5-oxo-1,4,5,6,7,8-hexahydro-3-quinolinenitriles (17-21) are described. Compounds 18 and 21, at the concentration of 0.3 mu M, proved to be the best blockers of the [Ca2+] overload induced by depolarization with high [K+] of SH-SY5Y neuroblastoma cells, with values of 63.8% and 50.4%, respectively. Most of the compounds induced a remarkable neuroprotective effect against toxicity caused by high [K+]-elicited [Ca2+] overload, and against H2O2-generated free radicals, in SH-SY5Y cells.
